Before few years I tested the response to cytokinin.
1/3MS medium supplemented with cytokinin 2.3 µM and auxin 0.5 µM
Cytokinin
KINETIN [ 6-furfurylaminopurine ]
trans-ZEATIN [6-((E)-4-hydroxy-3-methylbut-2-enylamino)purine]
N6 BENZYLADENINE [6 benzylaminopurine]
MoBO meta-methoxy benzylaminopurin-ribosid
Auxin
IBA - [4-(3-indolyl)butyric acid]
KINETIN
BAP
MoBO
trans-ZEATIN
Most effective was combination trans ZEATIN + IBA
